Let’s reiterate that the debate is primarily about causation: Warmists say it is mostly/solely caused by Mankind, especially our use of fossil fuels (which Warmists mostly refuse to give up themselves). Skeptics say the warming during the Modern Warm Period is mostly/solely natural. At that point we can get into the debate about Man’s contributions, such as true global changes, land use, urban heat island effect, etc. Warmists state that this warm period is utterly and completely different from previous warm periods because of industrialization, whining as they type on their corporate made laptop/tablet/smartphone as a they sip a corporate made latte made with beans shipped from another country, made in a corporate built building which has evil ice makers, which they picked up in their fossil fueled vehicles, while they sit on their corporate made couches in their homes which use lots of electricity. Anyhow, another dagger in the heart of the screeching about man mad global warming/climate change/climate disruption
West Coast warming linked to naturally occurring changes
Naturally occurring changes in winds, not human-caused climate change, are responsible for most of the warming on land and in the sea along the West Coast of North America over the last century, a study has found.
The analysis challenges assumptions that the buildup of greenhouse gases in the atmosphere has been a significant driver of the increase in temperatures observed over many decades in the ocean and along the coastline from Alaska to California.
Changes in ocean circulation as a result of weaker winds were the main cause of about 1 degree Fahrenheit of warming in the northeast Pacific Ocean and nearby coastal land between 1900 and 2012, according to the analysis of ocean and air temperatures over that time. The study, conducted by researchers from the National Oceanic and Atmospheric Administration and the University of Washington, was published Monday by the Proceedings of the National Academy of Sciences.
These are changes that have been going on for billions of years. Little changes in natural forces can have large effects.
This latest research shows that similar changes in atmospheric and ocean circulation can drive trends that last a century or longer, overshadowing the effects of human-generated increase in greenhouse gases, the study’s authors said.
Of course, the LA Times had to reach out to a hyper-alarmist (and fossil fuels using hypocrite)
Kevin Trenberth, a climate scientist at the National Center for Atmospheric Research in Boulder, Colo., who was not involved in the study, said its conclusions about long-term trends were probably overstated because the quality of data from the early 20th century was poor and unreliable. The results may also reflect the fact that the northeast Pacific is an area of the globe where past studies have shown the “signal” of climate change is low relative to the “noise” of natural variability.
Oh, OK, so now data from the early 20th century is meaningless. But, of course. Another excuse when Science shows Warmist idiocy is wrong.
